And gnutv does 'all' layers ?
I can see in the myth logs that it does this:

But then there is no file.

my gnutv cronjobs gives this:

Start recording De Wereld Draait Door on channel Nederland 3 as /storage/recordings_dvbc/2011-07-11 19.30 De Wereld Draait Door (DTV).mpg for 4200 seconds
exec gnutv -timeout 4200 -adapter 3 -channels /home/mythtv/ziggo.conf -out file "/storage/recordings_dvbc/2011-07-11 19.30 De Wereld Draait Door (DTV).mpg" "Nederland 3"
CAM Application type: 01
CAM Application manufacturer: 4a20
CAM Manufacturer code: 4a20
CAM Menu string: AlphaCrypt
CAM supports the following ca system ids:
Using frontend "FireDTV C/CI", type DVB-C
status SCVYL | signal ff00 | snr 1f1f | ber 00000000 | unc 00000000 | FE_HAS_LOCK
Received new PMT - sending to CAM...

and records without a hitch but it is a pain to alter the cronjobs by 
hand and I don't want to re-invent the wheel and create some elaborate 
database scanning routine to do it automatically. MythTV is working on 
the FTA DVB-C and DVB_S satellite channels perfectly. Just this small 
annoying issue with setting up the inital tuning and CI stuff. And you 
can not use an external channel changer script with the FireDTV from 
Myth (AFAIK) otherwise I would have gnutv do the initial tuning and let 
Myth do the recording.

P.S. before someone goes into a fit: this is an offical (payed for) 
Ziggo smartcard in an Alphacrypt CI module. Nothing illegal.
